[Freeciv-Dev] (PR#9856) RFC: caravans advisor

["Benoit Hudson" <bh@xxxxxxxxxxxxxxxxxxx>]

<URL: http://bugs.freeciv.org/Ticket/Display.html?id=9856 >

Latest update.

- bug and doc fixes in caravan.[ch]
- more info in gotodlg.c

The gotodlg code is crap, but it's the best way I could figure out how to fit 
it in the GUI 
without learning gtk.  It should *not* be committed as-is -- for one, it should 
be toolkit-
agnostic.  For another, it's way too hard to read right now.

The caravans part has a bug I haven't tracked down, where once in a while it 
thinks it can 
establish a new trade route (and so it thinks it's worth a lot), but actually 
it can't.  In my 
experience, this situation is rare.

It should be simple to add this to the ai_manage_caravan and use it to find the 
best 
destination, but I haven't tested that.
